MUNITION CASING.

Application filed May 16,

To all whom it may concern:

Be it known that I, VIoroR MAUCK, a citizen of the United States, residing at Norristown, in the county of Montgomery and State of Pennsylvania, have invented a certain new and useful Improvement in Munition Casings, whereof the following is a specification, reference being had to the accompanying drawing.

The United States Government at present requires munition casings each having a ring on the bottom of a. precisely dimensioned outside diameter, larger than the body of the casing, and known as the stowage diameter of the casing, and it is the practice to make such casings with a solid bronze ring fixed upon the body of the casing, independently of the bottom closure of the casing. Such construction is not only extremely costly, but adds very materially to the weight of the casings in proportion to their volumetric capacity. Therefore, it is an object of my invention to provide a casing presenting a precisely dimensioned outside diameter at its bottom by means less costly and lighter in weight than the bronze structure aforesaid. As'hereinafter described, my in vention affords the stowage diameter, above contemplated, by a single base piece of pressed sheet metal, preferably steel, which also forms the bottom of the casing and which is preferably connected with the latter by a single joint which may be preferably hermetically sealed by an oXy-acetylene welding operation.

My invention includes the various novel features of construction and arrangement hereinafter more definitely specified.

In the drawing; Fig. I is a longitudinal sectional view of a casing conveniently embodying my invention.

Fig. 11 is an inverted casing.

In said figures; the body of the casing 1 is conveniently cylindrical, but may be of any other suitable configuration. The base member 2 is annular, forms a pedestal directly supporting said casing, and has a stiffening shoulder 3 of the internal configuration of said body 1 conveniently formed by recessing said base member coextensively with the cross sectional area of said body 1, as indicated. Such construction affords an annular seat l for the casing, larger in diameter than its body, and the stowage diameter of the casing is presented by the anplan view of said Specification of Letters Patent.

nular flange 5 on said base member, which may be cylindrical, or otherwise shaped. The upper edge 6 of said base member 2 is preferably converged into contact with the outside of said body 1 and connected therewith by an autogenously welded seam 7, conveniently produced by an oXy-acetylene welding operation, but producible by an electric welding operation. As shown in Fig. 1, said upper edge 6 of said base memher 2 is preferably converged to form a truncated cone. Such construction facili tates the stowage of a plurality of such casings, in that it does not afford any ledge upon which an adjoining casing may rest, but deflects adjoining casings into their proper spaced relation.

It may be observed that the construction above described not only affords a tightly fitted closure for the bottom of the body 1, preventing escape of the powder, cartridges, or other munitions encased by said body 1, but also affords a hermetically sealed air chamber 9 exterior to said body 1 and serving as a cushion to minimize'shocks to which such casings are inevitably subjected during transportation. Moreover, as said base flange 5 is preferably resilient; it is more durable in maintenance of the precise stowage diameter required than the ductile bronze rings heretofore employed.

Although I have not shown any closure for the top of the casing illustrated herein; it is to be understood that any suitable closure may be employed; for instance, such as is shown in my copending applications for Letters Patent of the United States respectively Serial Numbers 217,037 and 219,674.

I do not desire to limit myself to the precise details of construction and arrangement herein set forth as it is obvious that various modifications may be made therein without departing from the essential features of my invention as defined in the appended claims.

I claim:

1. In a munition casing, the combination with a cylindrical, tubular shell; of a base member for said casing, formed of a single piece of pressed sheet metal, forming a closure for said shell, including an annular shoulder fitted to the interior of said shell and formed by an inwardly recessed portion of said base member coextensive with the cross sectional area of said shell; said base member being thus recessed to substantially the thickness of the metal thereof; said base member presenting an annular plane pedes tal support, extending at right angles to the axis of said casing, exterior to saidshell and larger than the latter, and having a peripheral cylindrical flange extending in spaced relation with the outer circumference of said shell and presenting a precisely dimensioned stowage diameter; the upper edge. of said base member forming a truncated cone, inwardly converged into contact with said shell; and means uniting said base member to said shell,.solely at the upper edge of the former, and remote from the re-.
